Ultra Boost: Uncaged 'Energy Aqua'

One of the latest Ultraboosts - this time in the Ultra Boost Uncaged silhouette, is the Energy Aqua colourway. Featuring a light blue and white knitted upper, with a white Boost midsole and pearly white Continental rubber outsole, the real specialty of this shoe is the translucent blue heel counter, which hasn't been seen before on an Ultraboost. Only available in womens' sizes, these are a lovely pair for daily wear, particularly with the combined comfort of Primeknit and Boost. For these, you definitely need to get rid of those glitch laces for a clean and crisp pair of white waxed laces. You can find these in our collection of Ultraboost shoe laces. Grab your pair today!

This sizing chart is a guide only and is flexible depending on how you thread your laces. For those you enjoy tight threading, our recommended "untied" versions may be appropriate for tying. For those who enjoy particularly loose threading, a larger length may be more appropriate. It will also depend on the size of the shoe (for example some smaller Ultraboosts would be recommended as 36 inch, but larger ones as 45")

The best way to check a rough appropriate length is to measure the current laces in your shoes.
